Lung Recruitment and Postoperative CPAP (LRvsCPAP)

2017年3月25日 更新者:Hala Saad Abdel-Ghaffar、Assiut University

Lung Recruitment and Postoperative CPAP in Pediatric Laparoscopic Surgery

General anesthesia lowers FRC thereby promoting airway closure and absorption atelectasis. Alveolar recruitment manoeuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation.

研究概览

详细说明

General anesthesia lowers FRC thereby promoting airway closure and absorption atelectasis. Alveolar recruitment manoeuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation. However, the effect of recruitment manoeuvre is short lasting and does not extend to the post operative period. Postoperative CPAP keeps the lung open and can improve oxygenation in the early postoperative period.
